RADIATOR-CASING.

Specification of Letters Patent.

Patented May 4, 1.909.

Application filed March 7; 1908. Serial No. $19,717.

To (ll/T whom it may concern:

lie it known that I, ALraun I1. SGHELL- Jifallniilt. citizen of the United States, residing at \Yarren, in the county of arren and State of Pennsylvania, have invented certain new and useful Improvements in Radiator-Casings: and I do hereby declare the following to be. a full, clear, and exact description of the invention. such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to heating devices and more particularly to those which are used in systems in which indirect radiation enters as a factor.

The object.- of my invention is to produce a casing for a radiator, which may be termed alcnock down casing. of simple and inexpensive construction. My improved casing is so constructed as to make itpossible to ship it in sections closely packed together. and it maybe set up in place by any ordinary workman and without the use of nails or screws.

Another object which I have in view is to force the cold air entering the easing into close contact With the radiator, so that there will be no eddies, but on the contrary a constant outgoing stream of. air thormighlv heated by the radiator.

In order that my invention may be clearly understood, I ha ve illustrated 1t in the accompanying drawings. described it in the spe -ifioatiou following. and have more particularly pointed it. out in the claims. at the end thereof.

Figure l of the drawings is a perspective view of my im roved casing in operative position. Fig. 2 is a front elevation of the casing with the outer side ren'loved. Fig. 3 is a similar view with both front sides re moved. Fig. -l is a cross section of the easing. Figs. 5 and 6 are detail views of parts of my device. Fig. 7 is an interior View of a modification of my easing. Fig. 8 is a perspective View of the cold air distributor, forming a part of my device. and Fig. 9 is a similar view of a modification of thesame. Fig. 10 is a detail view showing the frame grooved.

Similar letters of reference indicate identical parts throughout.

A. represents a rectangular frame which may be made of any desirable material. but which for convenience l have shown as made of wood. This frame is designed to be firmly secured to the ceiling of a cellar or basement room in which the heating apparatus is located, and may be fastened to the joists of the room above in any desired manner.

The outer edges of the frame are provided with covering of sheet material, preferably galvanized iron, a which is preferably flanged outwardly at the upper sides of the frame, and bent inwardly at a right angle somewhat below the lower surface of the frame and then outwardly upon itself forming a. continuous longitudinal slot or groove (4 which extends entirely around the edges of the frame A, forming a joint X. I may if I desire, instead of this construction, omit the metal covering and form a groove in the edges of the frameitself.

The space a above the bent in portion of the coueringds designed to receive the top B of the casing, and hold it. in place. The edges of the frame A are also provided at intervals with pivotally mounted spring clips 71, or other suitable retaining devices.

0 represents a radiator of any desired construction. which is designed to be supported by rods (2 suspended upon cross rods or sect-ions of gas pipe set in the joists of a building. the rods 0 being provided at their lower ends with cross rods or channel irons which are adjnstably held in place by nuts r" fitting the screw threadei'l ends of said rods. Upon the channel irons the radiator rests. The rods pass through annular openings in the frame and it obvious that by providing collars and setserews. the said rods may be made to support the frame if desired.

The casing is provided with double side walls; an air space being left between them. The inner side walls D, D extend downwardly from the top of the casing to the base of the radiator and rest upon the channel irons and are held in place vertically by the rods (1 which pass outside of said inner walls by the radiator.

The ends of the casing are. preferably covered with asbestos paper. or other non-eonducting material. The edges of the bottom of the casing are bent inwardly and outwardly upon themselves in a manner similar to that already tit-SCl'lllttl in connection with the covering for the edges of the frame so as to form a longitudinal groove extending around the outside of the bottom of the form a groove extending vertically at bent inwardly, as are also the top and bottom edges ofthe ends of the casing. 3

The side edges of the ends arebent inwardly and outwardly upon themselves to the corners of the casing. The ends are also provided with the clips 7) near their side 10 edges.

In the construction shown in Fig. 2, at the endof the casing atwliich cold air is 'admitted, I provide an inner end wall G which extends from the frame. A to the base ot the radiator, and is oined to the. inner side walls D, D.

The air distributer I, is renioval'ily secured Y to theinner wall G. preferably in the manner already describethby means of the joint 3. The distributer may consist of a perforated plate or a wire screen, and extends entirely across one end of the casing, as

shown in Fig. 4.

l/Vithin the casing I provide two batlie plates E and K. The plate E adapted to rest on the radiator atthe forward end of the casing and extends diagonally upward toward the other end of the casing, being inserted in the space a.

A hinged flap g is provided on the inside of the wall G and extends along its entire width; the free end of the flap rests on the top of the plate E and prevents the air from passing between the radiator and the wall G.

The battle plate K is located under the rm diator, one end resting on the bottom of the casing and the other end upon a vertically adjustable support 7;, clearly shown in Fig. 6. The plate K is bent upward and backward at an angle at its rear end, as at 7.1 to' force the cold air into contact with the radiator.

It will be noted that the distance between the rear ends of the battle plates is greater than that between their forward ends, to

accommodate the expansive force of the heated air it contacts with the radiator.

The casing is so designed as to size, that the radiating points '2' of the radiator will be very'close to, but will not quite touch, the innerside walls of the casing.

Suitable inlet openingsL and outlet openings M are providedin the front and rear walls of the casing for the passage of air currents, but they may be located elsewhere however.

In put-ting my improved casing together, the frame A is first firmly secured to the joists in the ceiling, The hanger rods are then put in place, passing through the holes provided therefor in the frame. The channel irons are then placed on the rods and the radiator is put into position thereon. The inner side walls are next placed, being inserted between the rods and the radiator.

The ballle plate IQ is then put. in place as shown. The, ends of the casing are then placed. the bent" in edges being inserted in the. longitudinal groove 41" and held by turning the spring clips I). The bottom of the casing is then put in place and also the bafile plate K. placed and the. distributer secured thereto. The outersides are then put in place, the bent in edges being inserted in the horizontal and vertical grooves a and the casing is complete, and practically air tight owing to the tight joints formed by the grooves and the insertion of the edges of the. sides. The sides are held in place by turning the spring clips I).

The operation of the device is apparent.

pansion by the widening of the distance between the rear ends of the ba'llle plates. The heated air passes through the outlet of the casing, whence it may be carried to any desired point of a building.

I have shown a single radiator provided with my improved. casing, but it is obvious that my casing may be used in systems, and a number of radiators and casings used, each casing communicating with a room of a building.
